CAPS — The long-ago predicted Central American alien border surge is here, and has put pressure not only on United States immigration officials, but also on Mexico. Despite having more limited financial wherewithal than the U.S., Mexico is doing its part – perhaps even more than the Obama administration – to stem the illegal immigrant tide.

In an interview with Reuters, Mexico’s Deputy Interior Minister for Migration Humberto Roque Villanueva said that his country is “at the limit” of its resources. Little wonder that Mexico is feeling the pressure. A recent U.S. Customs and Border Protection report showed that number of families stopped at the U.S.-Mexico border jumped 122 percent between October 2015 and April 2016 from the same period a year earlier. In 2015, Mexico detained 190,000 would-be illegal immigrants, twice the 2012 total.

As is its well-established practice, the Obama administration ignores the mounting illegal border crosser problem. A DHS representative had no comment when asked if his agency planned to send more border patrol agents to work with the understaffed Mexican officials. Roque Villanueva, however, said he was unaware of any possibility that DHS would send help. The only DHS agents Roque Villanueva knows of on the U.S.-Mexico border are trainees.

Summing up the threat that open borders represent to the U.S., Roque Villanueva said that “Americans are not so concerned about how many Central Americans get through, but rather about making sure nobody with even the slightest chance of being a terrorist does.”

Roque Villanueva’s statement is only half true. Americans are deeply concerned that open borders represent an easy opportunity for terrorists to enter. But citizens also are gravely concerned about Central American aliens’ border surge, and its economic and societal effects on America.
